Re: What's with the slime??
But what is 'normal'? I had ~200+ little barnacles per sq ft. Does that count as 'retarded growth' or is my bottom paint shot?
Yes, your paint is shot. Most anti fouling paints (when in good condition) will work very well against higher forms of fouling organisms (like barnacles.) They perform less well against lower forms (like algae) which is why the "anti slime" paint formulations came into being and are so popular. But the bottom line is; if you have a serious barnacle infestation on your hull, you need new paint.
Any suggestions on what to do?
Should I pull the boat and power wash them off? Just hire a diver to clean the bottom? Or should I pull it and put on a new layer of bottom coat?
At this point, anything but a new bottom is just a bandaid. But consider giving a local hull cleaner some work before you haul.
